Evolutionary loss of a signalling colour is linked to increased response to conspecific chemicals
Vital Garcia, Cuauhcihuatl (2021-03-31)Behavioural responses to communicative signals combine input from multiple sensory modalities and signal compensation theory predicts that evolutionary shifts in one sensory modality could impact the response to signals ... -
Information out of the blue: phenotypic correlates of abdominal color patches in Sceloporus lizards
Vital Garcia, Cuauhcihuatl; Zúñiga-Vega, Jaime; Pruet, Jake; Ossip-Drahos, Alison; Campos, Stephanie; Seddon, Ryan; Price, Savannah; Romero-Diaz, Cristina; Rivera, Julio; Hews, Diana; Martins, Emilia; Castillo, Ricardo (2021-12-01)Colorful ornaments are important visual signals for animal communication that can provide critical information about the quality of the signaler. In this study, we focused on different color characteristics of the abdominal ... -
Losing the trait without losing the signal: Evolutionary shifts in communicative colour signalling
Vital Garcia, Cuauhcihuatl (2019-04-01)Colour signalling traits are often lost over evolutionary time, perhaps because they increase vulnerability to visual predators or lose relevance in terms of sexual selection. Here, we used spectrometric and phylogenetic ... -
Volatile fatty acid and aldehyde abundances evolve with behavior and habitat temperature in Sceloporus lizards
Vital Garcia, Cuauhcihuatl (2020-05-20)Animal signals evolve by striking a balance between the need to convey information through particular habitats and the limitations of what types of signals can most easily be produced and perceived. Here, we present new ...
